My networking skills are non-existant, so beware of stupidity. I am writing software which needs to read users from Active Directory. I have written some code and I need to test it. I am running a Vista Home machine. I need to add some test values into Active Directory users but it needs to connect to a domain/domain controller. When I try to add a DNS server using my own computer, it says DNS server is not running. When I try to add a DNS server using my ISP, it says DNS server is not a Windows 2003 Server.. etc. So basically, is there anyting I can do to setup some sort of a local DNS server to just get my code tested?
